URL形式下如何进行PUT操作

一个签名URL的python 实现例子。
        '''
        Test put object with Signed URL
        '''
        host = get_host()
        method = "PUT"
        bucket = "test"   time.strftime("%Y-%b-%d%H-%M-%S").lower()
        object = "test_object"
        url = "/"   bucket   "/"   object
        resource = "/"   bucket   "/"   object
        content_type = "text/plain"
        #1. create a bucket
        res = self.oss.put_bucket(bucket)
        self.assertEqual(res.status, 200)

        #2.sign a URL with put method
        headers = {}
        headers["Content-Type"] = content_type
        headers["x-oss-meta-test"] = content_type
        timeout = 60
        url_with_auth = self.oss.sign_url_auth_with_expire_time(method, url, headers, resource, timeout)

        #3.get a normal HTTP connect and send content to object
        conn = get_conn_by_host(host)
        conn.putrequest(method, url_with_auth)
        filesize = os.path.getsize(self.put_file)
        conn.putheader("Content-Length", str(filesize))
        conn.putheader("Content-Type", content_type)
        conn.putheader("Content-Language", content_type)
        conn.putheader("x-oss-meta-test", content_type)
        conn.endheaders()
        original_content = ""
        fp = open(self.put_file, "rb")
        l = fp.read(self.oss.SendBufferSize)
        while len(l) > 0:
            conn.send(l)
            l = fp.read(self.oss.SendBufferSize)
            original_content  = l
        res = conn.getresponse()

科普下：
浏览器是不支持put操作的。

如果您使用的是Java SDK，可以使用OSSClient#generatePresignedUrl方法生成一个签名了的URL，然后使用HTTP访问的库上传Object。生成URL的参数可以参见这个方法的帮助和GeneratePresignedUrlRequest类的说明。

如果您没有使用Java SDK。可以参考OSS的《API手册》关于在URL中包含签名一节，动手创建URL
